Finalists were evaluated by the BUILDINGS editorial staff for the money-saving qualities they offer to building owners and facility managers in areas such as energy efficiency, water savings and maintenance.Solarban 90 low-emissivity (low-e) glass is engineered with advanced “quad-silver” coating technology that enables it to combine industry-leading solar control performance with a true neutral-reflective clear-glass aesthetic.
Combined with clear glass in a standard 1-inch insulating glass unit (IGU), Solarban 90 glass has a solar-heat-gain coefficient (SHGC) of 0.23, a 15 percent improvement over Solarban 70XL glass, the industry’s most widely specified triple-silver-coated solar control, low-e glass.
The same configuration produces visible light transmittance (VLT) of 51 percent and an exceptional light-to-solar gain (LSG) ratio of 2.22. Interior and exterior reflectance rates are 12 percent and 19 percent, respectively.
Earlier energy modeling of Solarban 70XL glass on a prototype 12-story office building shows that 10-year energy savings related to heating and cooling can exceed $1.5 million (compared to the same prototype building glazed with conventional clear-glass IGUs) through lower equipment costs and reduced energy use.
Because Solarban 90 glass has better solar control than Solarban 70XL glass, architects and glaziers can anticipate even greater energy savings.
In addition to supporting the use of smaller heating and cooling systems to reduce initial capital expenditures and long-term air-conditioning costs, Solarban 90 glass also enables architects to design buildings with larger expanses of glass to promote daylighting, diminish the need for artificial lighting and connect building occupants to the outdoors.
Solarban 90 glass meets requirements of the CRADLE TO CRADLE CERTIFIED™ products program at the Bronze level, which helps architects earn credits in the LEED® green building program for their projects.
